The announcement in a Google blog post came as the web titan sought to burnish the Glass image ahead of its expected debut in the US market this year.

Google last week sent out a release to debunk Glass myths including that it invades privacy, distracts wearers, and is for “technology-worshipping geeks.”

“If someone wants to secretly record you, there are much, much better cameras out there than one you wear conspicuously on your face and that lights up every time you give a voice command, or press a button,” Google said.

“If a company sought to design a secret spy device, they could do a better job than Glass.”

Google in February gave early adopters of its Internet-connected eyewear a bit of advice: don’t be “Glassholes.”

It was the final suggestion in a recommended code of conduct posted online for software developers and others taking part in an Explorer program providing early access to Google Glass.

The Internet titan appeared intent on avoiding the kinds of caustic run-ins that have seen some Glass wearers tossed from eateries, pubs or other establishments due to concerns over camera capabilities built into devices.

Don’t be “creepy or rude (aka, a “Glasshole”),” Google said in a guide posted online for Explorer program members.

“Respect others and if they have questions about Glass don’t get snappy.”

Google suggest Glass wearers be polite and offer demonstrations to possibly win over the wary. Glass fans were advised it is proper to follow the same rules set down for smartphone use in businesses.
